[patch #9757] Fix ATtiny817 Xplained Mini programmer

[Sven]

Follow-up Comment #6, patch #9757 (project avrdude):

Hi Jörg,

it took me some time to verify this because between me proposing this patch
and your comment, a regression has been introduced: The last revision that my
patch works on is r1435. r1436 breaks this programmer again—even with my
patch applied. See the extra verbose output for r1436 with my originally
suggested patch attached at the end of this post.

On r1435, I tried your patch. It works just as well as my proposed patch. I
agree that your patch is cleaner if it's safe to assume that programmers have
only up to one ID.
